2G/3G Shared Distributed Base Station System Design

3G base station as a wireless communication system is the most important part of itsfunctionality and cost control, with the popularity of3G has a higher demand.2G base stationafter years of optimization, wireless coverage is already relatively complete, so building aWCDMA base station antenna direction and inclination can be considered and2G antennapublic, but the original site may exist the problem of lack of space. Its unique modulardistributed base station, using the advantages of the old equipment, site resources,construction and compact, providing direction to solve this problem.The departure from the operational status of the provider of mobile communicationnetwork and its cost, network optimization problem, and focuses on the concept of distributedbase stations in wireless mobile communication system, system parameters, systemcomponents, and distributed base station in the WCDMA wireless communication systemsengineeringthe practical application in the construction and analysis from the engineeringpoint of view, as well as construction costs, the investigation of the basic processes of theWCDMA base station and wireless network planning and design programs based on adistributed base station, given the specific steps and data needed to complete design, andfinally combined with China UnicomShantou Branch network coverage and the proportion ofthe population of the W sector network parameters, and illustrate its low energy consumptionof distributed base station data running through the base station, fast and flexible deployment,saving room space and manpower advantages in actual commercialvalidation of distributedbase stations to save room space, free feeder loss, battery saving, the equipment electricityand air conditioning electricity obvious advantages.This paper focuses on the innovative design of the distributed2G/3G base stationco located, that uses a distributed base station in order to optimize the network,2G/3Gdevices at the same time share the same location of the base station, thus saving a site, theconstruction, the cost of laying linesavoid redundant construction waste. Such sharing2G/3Gbase station design, also has an important role in reference to4G construction will be carriedout.In this paper, a distributed base station location and migration algorithm proposed thereality base station site subject to the constraints of the restricted area, and may need to berelocated, an analog anti particle motion of the gravitational field base station location andmigration algorithmand combined with the genetic algorithm, to study the feasibility andperformance of the algorithm. This paper presents a distributed base station location and migration algorithm, give full play to the actual engineering manipulation distributed basestation Modular design and small volume, the choice of the site also makes it easier, and inthe existing3G base station will also be able to smoothly upgrade to LTE engineering practiceto validate and improve.
